hEndermanFix is a lightweight plugin that keeps Endermen focused on nearby Endermites.
The plugin automatically tracks Endermen and Endermites, searches for the closest valid Endermite in a configurable radius, and forces Endermen to target it. It can also mark Endermites as player-spawned and force Endermen AI/aware state before applying the target.
No commands, permissions, databases or extra dependencies are required.

How It Works
When an Endermite appears in the world, hEndermanFix registers it and checks nearby entities.
If nearby Endermen are found, the plugin starts tracking them and repeatedly updates their target to the nearest valid Endermite inside the configured radius.
The plugin also scans already loaded worlds on startup, so existing Endermen and Endermites can be handled without waiting for new entities to spawn.
Entity Tracking
The plugin listens for:

• Entity add events.
• Entity remove events.
• Entity death events.

This allows hEndermanFix to keep its internal entity lists clean and avoid tracking invalid or dead entities.
Target Updates
During each check, the plugin:

• Removes invalid Endermites from tracking.
• Finds the nearest Endermite for each tracked Enderman.
• Checks that both entities are in the same world.
• Applies the target if needed.
• Removes Endermen that no longer have valid Endermites nearby after too many missed checks.

This keeps the system focused only on active and relevant entities.
